4.1 Tools Required

You will need the following tools to complete the removal and replacement procedures: Magnetic screwdriver Phillips P0 screwdriver Torx8 screwdriver 5.0-mm socket for system board screw locks Flat-bladed screwdriver
4.2 Service Considerations
The following sections include some of the considerations that you should keep in mind during disassembly and assembly procedures.
As you remove each subassembly from the computer, place the subassembly (and all accompanying screws) away from
the work area to prevent damage.

Plastic Parts

Using excessive force during disassembly and reassembly can damage plastic parts. Use care when handling the plastic parts. Apply pressure only at the points designated in the maintenance instructions.

Cables and Connectors

CAUTION: When servicing the computer, be sure that cables are placed in their proper locations during the reassembly process. Improper cable placement can damage the computer.
Cables must be handled with extreme care to avoid damage. Apply only the tension required to unseat or seat the cables during removal and insertion. Handle cables by the connector whenever possible. In all cases, avoid bending, twisting, or tearing cables. Be sure that cables are routed in such a way that they cannot be caught or snagged by parts being removed or replaced. Handle flex cables with extreme care; these cables tear easily.
4.3 Preventing Damage to Removable Drives
Removable drives are fragile components that must be handled with care. To prevent damage to the computer, damage to a removable drive, or loss of information, observe the following precautions: Before removing or inserting a hard drive, shut down the computer. If you are unsure whether the computer is off or in hibernation, turn the computer on, and then shut it down through the operating system. Before removing a diskette drive or optical drive, be sure that a diskette or disc is not in the drive and be sure that the optical drive tray is closed. Before handling a drive, be sure that you are discharged of static electricity. While handling a drive, avoid touching the connector. Handle drives on surfaces covered with at least one inch of shock-proof foam. Avoid dropping drives from any height onto any surface. After removing a hard drive, an optical drive, or a diskette drive, place it in a static-proof bag. Avoid exposing a hard drive to products that have magnetic fields, such as monitors or speakers. Avoid exposing a drive to temperature extremes or liquids. If a drive must be mailed, place the drive in a bubble pack mailer or other suitable form of protective packaging and label the package FRAGILE: Handle With Care.
